By the fourth grade, I graduated to an erector set and spent many happy hours constructing devices of unknown purpose where the main design criterion was to maximize the number of moving parts and overall size.

Suppose you had a small electrical fire and... a structural engineer [looked] at your home's wiring [and] reports that the wiring is "shot" and there is a 50% chance that your house would burn down in the next few years unless you replace all the wiring. The job will cost $20,000... so you get an independent assessment. The next engineer agrees with the first warning. You can either continue to shop for additional evaluations until you find the one engineer in 1,000 that is willing to give you the answer you want, "Your family is not in danger" or you can change the wiring.

I've always been inspired by Dr. Martin Luther King, who articulated his Dream of an America where people are judged not by skin color but "by the content of their character." In the scientific world, people are judged by the content of their ideas. Advances are made with new insights, but the final arbitrator of any point of view are experiments that seek the unbiased truth, not information cherry picked to support a particular point of view.

So imagine a world 6 degrees warmer. It's not going to recognize geographical boundaries. It's not going to recognize anything. So agriculture regions today will be wiped out.

If other countries don't impose a cost on carbon, then we will be at a disadvantage...we would look at considering perhaps duties that would offset that cost.

Pick the right sized pot, don't pick a pot five times bigger, twice as big.
